REGULATOR FOR GAS=BURNERS.

SPECIFICATION forming part of Letters Patent No. 380,803, dated April 10, 1888. Application filed April 14, 1887. Serial No. 234,829. (No model.)

1'0 all whom it may concern.-

Be it known that I, WALTER MARsH J AOK- SON, of New York, in the county of New York and State of New York, hay e invented cer- 5 tain new and useful Improvements'in Regulators for Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description of the in vention,such as will enable others skilled in the art to which itappertains [O to make and use the same.

My invention relates to an improvement in pillars and regulators for gasburners.

In my pending application, filed December 13, 1.886, is shown a gas regulator that is I5 adapted to be combined with the interior of cylindrical pillar-burners. Some features of that application are embodied in my present application. It has been found in the manufacture of the regulator first mentioned thatit is difficult to rapidly produce the finished parts with cutting and forming dies in a perfeet manner and avoid frictional resistance between the working parts of the automatically operated regulator. i The object of my present invention is to perfeet the details of the regulator shown in my pending applica'tion, filed December 13, 1886, Serial N 0. 221,450, and by a change of construction of portions of the same and the addition of an important element I have produced a gas-regulator for pillar-burners that is perfect in its operation and that can be cut and formed complete by machinery at a low initial cost.

Referring to the drawings making a part of this specification, Figure 1 is a longitudinal section of the regulator with the improved features embodied. Fig. 2 is a longitudinal view of the regulator in a burner-pillar, the pillar 0 and regulator being shown in section taken on an axial line. Fig. 3 is a detached view of the base-ring upon which rests the sliding interior chamber of the automatic regulator. Fig. 4 is a View of a modified form of gas-regulator.

A represents the outer cylinder or shell of the gas-regulator, made of sheet metal cut, stamped, spun, or raised by dies into form. The cylinder A has a head, a, that is integral with its cylindrical body, and near the lower 50 edge, a an offset is formed at a, which produces an enlargement, b, of the cylinder A, the purpose of which will be explained.

A suitable distance below the head a one or more perforations, c, are made in the cylindrical wall of the shell A. The plain cylindrical chamber A is of such a relative diameter to the interior caliber of the outer cylinder, A, that it willslide therein freely. This inner chamber, A, is provided with an integral head, upon the top surface of which the small projections b are formed, these being adapted to prevent the adjacent surfaces of the inner chamber and outer cylindrical shell from having close contact. The head is also perforated centrally to permit the passage of gas. Inner chamber, A, is of such a length proportionately that its free lower edge will project slightly below the offset edge a of the cylindrical enlargement b, integrally formed on the outer shell, A, when the projections 12 are in contact with the head of the shell A. Thein ner chamber or shell, A, is supported to slide freely in its containingshell A by the basering B, made of sheetmetal cut, spun, stamped, or formed by dies into shape, and is of a diamter to 'fit tightly within the enlarged part of the shell A. Base-ring B has a slight flange, e, turned on its lower edge, and is further provided with one or more, preferably three, cars, e, bent at a right angle to the body of the ring. The flange e is designed to stiffen the light sheetmetal ring, and the ears 6 are intended to support the inner chamber, A, when these parts are adjusted together.

In assembling the parts of the regulator the 8 5 inner chamber, A, is inserted into the shell A, and the free edge of the base-ring B is entered into the enlarged portion b of the shell A. The ring Bis then forced into place. The ears e, projecting beneath the free lower edge of the chamber A, prevent it from an improper depression.

The parts of the device should be so constructed and arranged that the top surface of the perforated head of the inner chamber, A, will line with the lower edge of the perforations in the outer shell, A, and thus permit a free passage of gas through them, this position of the inner chamber allowing its lower edge to rest on the ears 6 of the base-ring B, and I90 sliding gas-chamber A is shown.

such an adjustment will continue while a regular flow of gas at normal pressure is passing through the pillar-burner into which this regulator is placed; but in case of a sudden increase in the pressure of gas flowing to the burner this pressure will be received upon the interior surface of the head of the inner chamber, A, and in consequence of the inability of the graduated orifice d in this head to pass the volume of gas the chamber A will be forced to rise until its projections b are in contact with the inner face of the shellA, and the top edge of the inner chamber, A, is just above the line of the holes 0 in the side wall of the shell A, thus cutting off the outflow of gas from the space above the head of the inner chamber, which space is provided by the abutment of the projections b on the head of the shell A. The gas will now have equal pressure on each side of the heady of the inner chamber, A, and the chamber will instantly fall by gravity to open a passage for gas, the flow through the holes a being thus automatically adjusted to'yield a steady light with a uniform pressure in the burner-tip, regardless of varying pressures sustained bythe regulator.

In Fig. 4 a modified form of support for the In this style of regulator the features are identical as relates to the construction of the cylindrical shell A and its enlarged portion 1), as well as the inner chamber, A, the alteration being in the manner of holding the inner chamber intact with the shell A, and affording it"a support when it is in a depressed position in relation to the gas-escape orifices c. In this modification the base-ring B is dispensed with, and the necessary ears to sustain the chamber A are produced by slitting the portion b of the shell A from the lower edge upwardly at proper intervals, and by bending ears or lugs i inwardly at right angles to the shell to form ears or lugs upon which the chamber A may be seated, it being understood that this chamber is inserted in place prior to the bending of the integral lugs i. The distance of these lugs should be such in relation to the height of the chamber A that this chamber will have its head 9 on a line with the lower edges of the holes 0, forthe purpose previously explained.

The burner-pillar F, in which the regulator just described is located, has an ofiset or slight shoulder, 0, formed on its interior surface at such a proper point that the edge a of the enlarged portion b of the outer shell of the regulator will be engaged by this shoulder 0 to define the position of the regulator in the pillar or tubular column of the burner and prevent an upward displacement of this regulator.

Having fullydescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a regulator for gas-burners, the combination, with an outer shell diametrically enlarged at its open end, of an inner movable shell and inwardly-projecting lugs or cars for holding the inner shell in position, substantially as set forth.

2. In a regulator for gas-burners, the combination, with a cylindrical shell having an enlarged offset portion formed integral near its base and perforations in its side wall, of an interior sliding chamber having a perforated head, and a base-ring provided with ears to support the inner chamber, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
